Review: Seemingly overpriced, but so worth it! - I have been getting into fixing up guitars and had really like the idea of the Fret Kisser, but it had always seemed too pricey for a non-professional. However, I saw this set as a Black Friday deal where the whole shebang was listed for around 80 bucks and I couldn't resist. I am happy to say that it works extremely well for doing those touch-ups to a fret board, and avoiding any 'beam leveling' which is usually overkill. As for the other items, I was pleasantly surprised at the quality of the fret rocker! I had recently purchased a generic fret rocker and thought that it was perfectly serviceable. But when I had the StewMac to compare it to, I realized that the generic one was actually not accurate. The generic was giving me 'rocking' just by virtue of the fact that I had it slightly uneven across the frets. The StewMac is about twice as thick as the generic, and it is MUCH more accurate. This alone has possibly saved me hours of chasing 'ghost bumps' on my fretboard and doing unnecessary adjustments. All in all, I have no regrets. I guess sometimes you really do get what you pay for. I'm just glad that I was able to 'pay for' it a lot less than the normal price! The string gauge is great too!

## Questions & Answers

**Q: Why is this only 28.00 dollars on the StewMac website?**
A: I remember noticing it was cheaper on stew Mac but you had to pay for shipping I think they’re making up the difference in shipping cost but I’m not sure that’s just my guess.

**Q: Does it come with instructions?**
A: I do not remember it coming with instructions . It has four sides and the idea is to use it across three frets.  And you use whatever side is the right length for where  you are at on the neck closer to the nut you’ll use the long and closer to the pick ups you’ll use the shorter and the other two for in between those two extremes. I can tell you that I had purchased a cheaper one and had to send it back because it was not level so I bought the stew Mac and it was dead on accurate if you have  Unlevel Fretts  it will show you by rocking it back-and-forth if it does not rock it’s level and you need to check it not just in the center of the frets but from the lower E to the high E  because they can be  off in more than one spot. Hope this helps you.

**Q: $40 for a strraight edge? what am I missing?**
A: The length of each side is different to check 2 frets and up to multiple frets. Your paying for multiple length strait edges in one tool. 40 dollars is expensive for a piece of stainless with a straight edge. There is others on the internet cheaper, not from stewmac. Your not missing nothing, its no different from buying a tool from Snap On versus Harbor Freight.

High quality. A valuable tool to have if you work on your instruments.

### ⭐⭐⭐⭐⭐ Don't buy from anyone else, just buy this. You'll be glad you did!
*by N***N on December 10, 2025*

I've enjoyed playing guitar for years (a few high dollar vintage ESP's and Ibanez guitars, however I never had the proper tools for adjusting for fret wear, or did I have measuring tools that gave me an indication of how it was set-up. The quality of these tools cannot be understated. Thick metal, precision machined, laser-etched (not just printed on). I was lucky enough to pick up this set during a sale (for around $70 from over$100), but it was in my list/cart regardless and I would've happily purchased this kit without saving money. If you play guitar, you'll need these tools...period! And don't settle for lesser quality 'no-name/cloned junk' copies here on Amazon. They may work OK in the interim, but they will not last. Those cheap, poorly manufactured products will wear out and you'll be buying them again one day or worse yet, trash your fretboard. I will/would buy from Stew Mac again and recommend this set for anyone who wants to take their guitar adjustments and maintenance seriously, you'll honestly get what you pay for! You'll see and feel confident in your purchase as soon as you peel the plastic off, WOW. -A happy customer (not a paid review!)
